About 5 years ago, a friend of mine called and said a friend of hers was in over her head with a serious problem horse and she was wondering if I was interested. The mare was in training at a local dressage barn and the trainer told the people to get rid of the horse, as it would never make a decent riding horse. I went to check out the mare, who was pushy, invasive, bucked constantly undersaddle, but very cute. My husband and I had just moved into a new house, and I asked the owners about the horse. They said that she was given to them and said the street that the horse lived on. I said "really, that's where I just moved, which house?" They said "last one on the right, with all the queen palms in front". Interestingly enough, it was the same house we just moved in. Keep in mind this is not a small horse community by any means.
Anyway, the mare moved in with us and right back to the same property that she came from. The neighbors said the mare had been so whacko that they wouldn't let their children near her in the past, she was unpredictable and neurotic. Five years later, with a little bit of work, she is my best lesson horse, showing successfully with small children, and doing everything from cow work to parades. I ran into her old owner a few weeks ago, who couldn't believe it was the same "untrainable" horse she sold me years ago. I always thought it was funny that she went right back where she came from.
